I got my 80 xs400 About a year ago. Got the carbs cleaned at a Yamaha garage immediately and it has been running great, until recently.
The bike has always been hard to start up when its been sitting for more than a few hours. It usually takes me 5-10 kicks on a warm day, 10-20 in the fall or winter. I never cared to much cause it's all part of the charm. I've also noticed the Battery (which is new) tends to loose it's charge pretty quickly and I need to recharge it. I can tell there is oil or gas leaking out of the head gasket as well, but this hasn't cause any problems. Other than these issues the bike would run smoothly.
There's the history, now for my problems:
Recently while driving the bike would die when it has to idle for more than 30 seconds -minute (At red lights and such). After getting it home by consistently feeding it gas. I notice the bike would bog down, and sometimes die if I opened the throttle to quickly, leading me to believe the mixture to lean.
Now, it takes a great deal of sweating to get the bike going again, It catches, starts up quickly and dies immediately, and repeats this until it eventually stays running.
Any ideas? suggestions? I'm pretty new at this but have been having learning a lot recently. Most of the work I've done on it has been body work/electrical but i'm looking forward to opening up more!
